, I recently moved into a new apartment and the light in the dining room was a simple bulb recessed into the ceiling which looked ugly. So I ordered a standard lightbulb extender and this fixture to replace the ugly lightbulb that was in the new dining room at my new location. It was very easy to install. Just install it like a lightbulb. Insert 5 standard size bulbs into 5 sockets and turn on the light. That's all. My new dining room light may not look fancy or stylish, but at least it works and looks significantly better than a regular large CFL bulb. In addition, 4 of the 5 sockets can be rotated to adjust the lighting angle. The fifth center bushing is fixed and does not rotate. Also, it is white in color to match most blankets. Works well enough in places where you have a simple ceiling lightbulb socket that you want to upgrade or replace. I rated this product 5 stars. There's nothing wrong with it and it works well enough for me!
